Abstract: PROBLEM TO BE SOLVED: To enhance the privacy of a caller without a complicated operation by permitting a communication terminal equipment to communicate a caller number only to a trustworthy communicatioin opposite party and automatically rejecting the report of the caller number to the communication opposite party except him. SOLUTION: The communication terminal equipment 100 obtains the telephone number of the opposite party executing communication with an input part 103. Then, a telephone directory database stored in a storage part 104 is retrieved with the inputted telephone number as a key. In result, it is judged whether or not the telephone number of the opposite party exists in the telephone directory database. When it is judged that it exists, a line control part 105 is controlled so as to dial an opposite party telephone number. In the meantime, when it is judged that the telephone number of the opposite party does not exist in the telephone directory database, an area code for rejecting the report of the caller number is dialled and, after that, the opposite party telephone number is dialled.

IPC: G01R33/035
Filed: 1978-09-11
Abstract: PURPOSE: To obtain a superconductive magnetism measuring instrument which provides the high-sensitivity and high-precision measurement of the intensity of a magnetic field under cryogenic temperature by using an easily-manufactured superconductive magnetism measuring element which is tolerant of thermal variation and vibration.  
     CONSTITUTION: Integral sweeper 10 generates an integral output of a constant voltage and its output becomes zero when a pulse signal is inputted. Constant- current power supply 11 supplied with that output supplies a current in proportion to the output to the superconductor and heater of superconductive measuring element 8. On detecting a voltage drop of more than approximate 10μV across the superconductor, normal conduction transfer detector 12 generates one output pulse. This output pulse is supplied to integral sweeper 10 and display unit 13. The output of constant current power supply 11 is supplied to display unit 13 as well. Only when receiving the output pulse, this display unit 13 samples the output current value of constant current power supply 11 and displays the sampling value. In this way, magnetic field intensity can automatically be measured by using superconductive magnetism measuring element 8.
